Problem
The mirror listener subscribes from the current date/time, this could result in any messages sent while the listener was down to be missed. This is ok for demonstration purposes, but not sufficient for production use.
Solution
Subscription should start from the consensus timestamp (+1 nano) of the last notification.
Alternatives
There are no alternatives that would ensure no loss of notifications.
